“More than this, it see fit seem that pollution, in large part related to traffic emissions, has an abrupt adverse effect on those with chronic diseases such as COPD and cardiovascular diseases.

“This influential study mandates action to radically reduce pollution at source to facilitate our cities and towns to be safe places to live in and move around.”
